IMPROVEMENT IN CORN-PLOWS.

Specification forming part of -Letters Patent No. 43,288 dated June 28,1864.

To all whom "it may concern:

Be it known that I, L. H. OAsroR, of Edington,in the county of Rock Island and State of Illinois, have invented a new and Improved Corn-Plow; and I do hereby declare that the followingis aful], clear, and exact description of the same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is a side sectional view of my invention, taken in the line or as, Fig. 2; Fig. 2, a front sectional view of the same, taken in the line y 51 Fig. 1.

Similar letters of reference indicate corre sponding parts in the two figures.

This invention relates to a new and improved means for adjusting or moving the plows laterally, so that the same may be made to conform to the sinuosit-ies of the rows of corn to prevent plants being plowed out of the ground while the implement is being drawn along; and the invention also relates to an improved means for raising the plows out of the ground when desired.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents an axle having a wheel, B, 011 each end of it, to which two bars, 0 G, are permanently attached, said bars projecting in front of the axle, and having a rectangular frame, D, attached to them by pins or a, said frame extending back over the axle A, and being allowed to work freely on the pins a a.

E represents the drivers seat, which is attached to inclined bars I) I), the front ends of which are secured one to eachbar O, and at the back parts of the bars I) b, underneath the drivers seat E, there is a shaft, F, the ends of which have arms 0 0 attached, to which the back part of theframe D is connected bylinks d 0?. One of the arms 0 has a lever, G, attached, said lever extending forward so as to be within convenient reaching distanceof the driver on the seat E. The frame D has plowstandards 6 attached to it, to which plows H of the usual or any proper form are secured, said plows being stationary or having no movement independently of the frame D. The standards e are attached to the outer longitudinal bars, f, of the frame, and to inner parallel joints h standards 1, whichjoints admit of a lateral movement of the standards land plows I, which are secured to them. The plows I are designed for plowing near to the rows of corn, the plows H loosening the earth and eradicating weeds between the rows. Thetwo plow-standards t t are connected by a bailshaped bar, J, the form of which is shown in Fig. 2, the lower ends of the bar J being connected to the standards 6 by pivots j, also shown in Fig. 2.

To each bar g of the frame D there is attached a bent lever, K, the lower ends of which are bent and notched so as to receive the inner edge of the bar J. The upper ends of the levers K are connected by links 70 to treadles L, the front ends of which are connected to the front end of the frame D by joints 1. The

back ends of the treadles L are within reach of the feet of the driver on the seat E, and it will be seen that by actuating these treadles the levers K will bemoved and made to bear against the bar J, and the standards 13 'i and plows I consequently moved laterally either to the right or left, as may be desired. In order to raise all the plows entirely out ofthe ground, the driver presses down the front end of the lever G, which causes the shaft F to turn, and

the arms 0 c and links (I (I will elevate the back part of the frame D. Thus by this simple' and efficient arrangement the plows'may be operated or adjusted with the greatest facility.

M represents the draft-pole, which is secured centrally in the front part of the frame D by a bolt, m. The back end of the draft-pole works underneath a plate, N, on the frame D, which is perforated with holes a, and a catch, 0, which is attached to an inclined arm, P, on

the back part of the draft-pole, seeares the latter in difi'erent positions, as may be desired, said catch being composed of a pin, which passes through the arm P and throughany of the holes a in the plate N, the pin being attached to a spring-lever,p, on the arm P. (See Fig. 1.) By shifting the draft-pole the machine may be greatly assisted in turning, and also guided with greater facility than usual.

The whiffletrees are attached to the end of a rope or chain, Q, which passes underneath pulleys q q, fitted to pendants r at each side of bars, 9, of said frame there are attached by I the frame D,said rope extending around pulleys s s at the back parts of the bars 0 0. By 2. The combination of the bars 0 0, frame this arrangement a simple and efficient draft- D, drivers seat E, rock-shaft F, links cl d, and equalizer is obtained. levers G c, all constructed, arranged, and em- Having'thus described myinvention, what I ployed substantially as described, for raisin g claim as new, and desire to secure by Letters the plows when required.
